In the Figure 3 is an enlarged View of a pdrtion form of the invention shown in Figures 1, 2 and 45 of Fig. 2 showing more in detail how the valve the Valve stem 20115: ?Y Wlth ah extehstem and an extension thereon is utilized to pull 21 e end of Whlch 15 threaded 22 over the side portion of the cover into proper tire the free end of; the valve stem as best shown protecting position on the outer side wall of the s- The other end of the tubular exten- Spare tire sion is secured by means of lock nuts 23 and 24 50 Figure 4' is a fragmentary sectional View Simi to a flattened portion 25 of the side disc 16. The lar to Figure 3 showing a modification of the nut iS disposed On One Side Of the side disc invention and in which the side portion of the and the nut 24 is disposed on the opposite sidespare tire cover is secured directly to the valve The outermost extremity of s extens on 21 stem rather than to an extension on the valve has disposed in it the usual air valve designated stem. Ienerally by reference character 26. Also. there is threaded over the outermost extremity of the extension 21 the usual valve cap 27.

It will .be noted that the valve stem 20 also has a conventional air valve 28 disposed therein as best shown in Figure 3, Of course it follows that when air is introduced'intp the valve stem extension 21, the air under pressure not only opens the valve 26 but also opens the valve 28 so as to enter the inner tube within the tire.

By tightening the nut 23 on the extension 21, it is possible to draw the side disc 16 up tight against the outer side of the spare tire 10. When it is desired to remove the cover from the tire, the valve cap 27 is first removed from the extension 21 and then the nut 23 is unthreaded from the extension. Thereafter the side disc 16 may be pulled laterally oil of the valve stem extension 21. I

In the'form of the invention which I have just described, the opening in the side disc 16' for accommodating the valve stem extension 21 is preferably circular and of a diameter slightly larger than that of the valve stem extension. On the other hand, in the modified form of the invention shown in Figs. 4 and 5, the opening is in the form of a bayonet slot 30 which includes an upwardly extending narrow slot portion designated by the reference character 31.

The side disc 16' in which this bayonet slot 30 is disposed is not formed with a flattened area such as the ring-like area 25 of the previously described disc 16 but instead is curved inwardly as indicated at 32. The valve stem 20' is adapted to extend through the bayonet slot 30 and has on its outermost end a valve cap 35.

The narrow part 31 of the bayonet slot 30 is of a width less than the diameter of the valve cap 35 so that if the valve stem is passed through the lower end of the slot 30 and thereafter raised upwardly, it is interlocked with the side disc 16'. In other words, the side disc 16 cannot thereafter be removed without either its 7 being raised off of the valve stem or the valve stem being moved downwardly to bring it into. the enlarged lower endof the bayonet slot 30 whereby the cap 35 may pass through the slot.

In the application of the side disc 16 to the cover, the side disc is first brought into such a position thatthe cap end of the valve stem 20 is'permitted to pass through the lower end of the bayonet slot 30. Thereafter the disc 16 is pushed downwardly whereby the valve stem is caused to move up into the narrow neck 31 of the bayonet slot.

I am aware that changes may be made and numerous details of construction'may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than is necessitated by the prior art.

I claim as my invention:

1. In a spare wheel and cover construction, a'tire including a relatively rigid valve stem, a side portion for disposition over a side of a wheel and having a valve stem opening therein and means associated with said side portion for securing said portion to they valve stem of the spare tire.

2. In a spare tire and cover construction including a side disc for disposition over an outer side wall of a spare tire, means for pulling said disc toward the tire including the valve stem of the spare tire.

3. In a spare tire and cover constructionineluding a side disc for disposition over an outer side wall of a spare tire, means for pulling said disc ,toward the tire including the valve stem of the spare tire, and a tubular extension on the stem projecting through an opening in said disc,

said disc being detachably fastened to said extension.
